Abstract

In January, 1954, the Bureau of Mineral Resources began diamond drilling in the Edith River, N.T., to test the grade and extent
of uranium mineralisation in two uranium-bearing deposits. The uranium mineral, mate-autunite, occurs in narrow siliceous
reef formations. Surface and drill core samples all returned less than 0.1% U3O8. Radiometric logging of the holes showed
no significant increase of radioactivity with depth. Shaft sinking proved the deposits to be small and lenticular.
